DESIRE E. VAN HOVE, OF JACKSON, MICHIGAN, ASSIGN'OR TO REYNOLDS SPRING GOIMIPANY, OF JACKSON, MlECH'IGAN.

srnnve srnuc'runn' Specification of Letters Patent.

Patented Aug. 16, 1921.

To all whom it may concern:

, Be it known that I, DESIRE H. VAN Hovn, a citizen of the United States, residin at Jackson, in the county of Jackson and tate of Michigan, have invented new and useful Improvements in Spring Structures, of which the following is a specification.

This invention relates to spring struc tures.

One object of the invention is to provide a spring structure for automobile or other seats, embodying among other characteristics, an edge for the structure designed to prevent sagging or swaying of the structure and affording a stiff spring structure for the support of the upholstery, and yet providing a structure capable of taking care of the varying Weights without danger of a complete compression of the springs, thereby providing for a soft and easy riding for the occupant of the seat.

Another object of the invention resides in the provision of a spring structure embodying upper and lower frames connected together by relatively stiff border springs within which is disposed a group of springs forming a center double-deck arrangement ofsprings surrounded by an intermediate frame in combination with the top truss or stay wires connected to the upper frame and to said intermediate frame, the adjacent truss or stay wires being arranged preferably in opposite direction with relation to each other.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and particularly pointed out in the appended claims, it being understood that such changes in the size, form, proportions and minor details as will be permitted under the appended claims may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawings:

Figure 1 is a top plan view of the invention.

Fig. 2 is an end elevation.

Fig. 3 is an enlarged detail cross-sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a detail perspectiveview of one of the clips employed in the structure.

Fig. 5 is a fragmentary perspective illustrating the manner of of the truss or stay wires to der frame.

Referring now more particularly to the accompanymg drawings the reference character Q indicates an upper border frame of wlre or any other suitable material and 7 lndicates a channeled or other suitable lower border frame, in this instance, having a wood insert 8 to which the lower edges of the facings of the upholstering material (not shown) may be secured, and also havlng a longitudinal groove 9 designed to receive and secure the lower convolutions of the border springs which latter are also supported upon the supporting bars 10 of channeled or other suitable formation. These border springs may be connected to the upper and lower border frames and to their supportmg means in any suitable manner, suitable clips 11 being used to secure them to the upper border frame. These border springs are preferably of the double cone type, as shown.

The character 12 indicates pairs of spring supporting bars and which are preferably of channeled shape and in the channels of which are secured in any suitable manner rows of springs 13, 14 and 15 which constitute the lower portion of a group of sprin forming a center double-deck structure These springs are of the double cone type, and are relatively short, compared with the border springs, being of a height substantially one-half of the height of the border springs; and of a gage of material of substantially the same gage as that of the border springs.

An intermediate'wire or other frame 16 is mounted upon and surrounds the springs 13, 14 and 15 at the upper ends of the latter. A wire netting or other suitable material 17 is stretched tightly'across this intermediate connecting one frame 16 and is secured thereto by means of suitable clips 18, to deaden sound between the springs.

A set of springs arranged in rows 19, 20 and 21 constitute the upper portion of the aforesaid center double-deck structure A and they are arranged upon the rows of sprlngs 13, 14.- and 15, respectively. These springs 19, 20 and 21 are of the double cone type but of lighter page Wire than the lower set of sprin 13 4 and 15, there being one of these lig ter' sprin s arranged directly over the upper boreach of the interior springs 13, l land 15 but separated therefrom by said wire netting 17. These upper and lower sets of springs are connected togther at their abutting ends and to the said intermediate frame by means of suitable clips 22, with the bases of all of said upper set of springs connected together by means of suitable clips 23, said clips 23 being arranged above the netting 17. The innermost springs of the lower set of interior springs are connected together at their upper ends beneath the netting 17 -by means of suitable clips 24. Clips 25 connect the said'intermediate frame 16 with the border springs, as shown, and clips 26 preferably connect the upper convolutions of the set of interior springs together and to the border springs, as shown.

Truss or stay wires 27 and 28 are employed, the stay wire 27 having its outer end 29 directed laterally and secured to the up- I per frame by means of a suitable clip 30 and having its opposite end laterally directed, as at 31, and secured to the farther side of the intermediate frame 16 by means of a suitable clip 32. The stay wire 28 is of the same formation as the stay wire 27 and it is secured to the upper border frame and to the intermediate frame in the same manner, but, as will be noted, the stay wire 28 extends in a direction opposite to the direction of the stay wire 27, such arrangement of the stay wires holding the entire structure against side thrusts and yet not affecting the resiliency of the structure.

If desired, there may be employed a supporting wire 33 which may extend longitudinally across the bottom of the structure and have its ends secured to the lower frame and to which some of the springs may have their lower ends connected, but whetherthe springs be connected to this stay wire 33,

the latter serves as a brace to strengthen the base of the structure.

What is claimed is:

1. In a spring structure, a frame, border springs connected to the frame, a group of upper and lower springs arranged within the border springs, the upper springs of said group being of lighter gage wire than the lower set of springs and of lighter gage wire than the border springs, a frame arranged within said border springs and connected to said group of springs, a wire netting stretched across the last mentioned frame and secured thereto and arranged between the upper and lower sets of springs of said group of springs, and connections be- .tween said second mentioned frame and certain of the border springs.

2. In a spring structure, an upper frame, a lower frame, border springs arranged between the upper and lower frames, a group of upper and lower springs arranged between the upper and lower frames and with in said border springs, a frame arranged be tween the upper and lower frames and within the border springs and connected to said group of springs, a wire netting stretched across the intermediate frame and secured thereto and arranged between the upper and lower sets of springs of said group of springs, connections between said intermediate frame and certain of the border springs, and diagonally disposed stay wires confined between the intermediate frame, and the upper frame and connected to opposite sides of the upper frame and to opposite sides of the intermediate frame.

3. In a spring structure, an upper frame, a lower frame, border springs arranged between the upper and lower frames and having connection therewith, a group of upper and lower springs arranged between the frames and within said border springs, an intermediate frame arranged between the upper and lower frames and within the border springs and connected to said grou of springs, and stay wire connections con ned between the upper frame and said intermediate frame and arranged in parallelism and extending downwardly in opposite directions from the upper frame and connected at opposite sides of the intermediate frame so as to prevent lateral thrusts of the intermediate frame.

4. In a spring structure, an upper frame, a lower frame, bordersprings arranged between the upper and lower frames, a group of upper and lower springs arranged be- 100 tween the frames and within said border springs, the upper springs of said group being of lighter gage wire than the lower set of springs and of lighter gage wire than the border springs, an intermediate frame arranged between the upper and lower frames and surrounding and connected to said group of springs and confined within the border springs, link connections between said intermediate frame and some of the border springs, and a stay wire connection between the upper frame and the intermediate frame, said stay wire having rigid connection with the upper frame and the intermediate frame.

5. In a spring structure, an upper frame, a lower frame, border springs arranged be tween the upper and lower frames, a group of upper and lower springs arranged between the frames and within said border springs, the upper springs of said group being of lighter gage wire than the lower set of springs and of lighter gage wire than the border springs, an intermediate frame arranged between the upper and lower frames and surrounding and connected to said group of springs and confined within the nected to the upper frame and also rigidly connected to said intermediate frame and confined between the upper frame and the intermediate frame and arranged between corresponding rows of springs.

6. In a spring structure, a frame, border springs connected to the frame, a group of upper and lower springs arranged within the border springs, a frame arranged within the border springs and surrounding said group of springs and connected to the group of springs, a staying means between the upper frame and the intermediate frame, means connecting the lower convolutions of the upper springs of said group of springs, and means connecting the upper convolutions of the lower set of springs of said group of springs.
